For industries that have hazardous wastes which need to be handled, there are systems which are established to ensure that such wastes are contained in ways that do not lead to spills or leaks. The concept of containment systems, as well as secondary containment systems, exists which help protect the workers, property as well as the environment from hazardous effects of toxic spills that might occur. The systems play a vital role to define the right ways hazardous materials need to be transported, stored, treated and disposed of. The regulations are laid down for different toxic waste substances as per the Environmental Protection Agency or EPA. For training on how to deal with toxic waste and other workplace safety courses please visit the Northern Safety Association.
THE Resource Conservation and Recovery Act that was issued by EPA in the mid-seventies define the requirements for handling of hazardous substances. When there are toxic chemicals or such wastes generated in industrial premises, there is the need to use the right kind of equipment for containing such materials. That is what containment systems are defined as by RCRA guidelines.
There are containment systems that are specifically designed for containing hazardous materials which are portable containers of certain material grades and classification. Containment systems or portable containers that are designed for handling toxic wastes usually comprise of wood grids, pallets, grated basins, and decks. There are specifications laid down to ensure that such containment systems hold toxic wastes as per a defined volume. Such specifications exist so that liquids do not spill out of such containers. For instance, if the containers are ventilated or grated these can have liquids dripping down. These containers also need to come with drainage valves to ensure safe drainage of toxic substances as required.
Secondary containment systems
These are defined separately by EPA. These are known as spill containment units which are used by businesses and vendors as required. These usually supplement the stationary units and are used to transport hazardous materials from one place to another. Such containers can range from drip trays, pipes, bunds, sumps, ventilation systems and others.
